I'd like crop an image in PHP and save the file. I know your supposed to use the GD library but i'm not sure how. Any ideas?
Thanks
You could use imagecopy
to crop a required part of an image. The command goes like this:
imagecopy (
resource $dst_im - the image object ,
resource $src_im - destination image ,
int $dst_x - x coordinate in the destination image (use 0) ,
int $dst_y - y coordinate in the destination image (use 0) ,
int $src_x - x coordinate in the source image you want to crop ,
int $src_y - y coordinate in the source image you want to crop ,
int $src_w - crop width ,
int $src_h - crop height
)
Code from PHP.net - a 80x40 px image is cropped from a source image
<?php
// Create image instances
$src = imagecreatefromgif('php.gif');
$dest = imagecreatetruecolor(80, 40);
// Copy
imagecopy($dest, $src, 0, 0, 20, 13, 80, 40);
// Output and free from memory
header('Content-Type: image/gif');
imagegif($dest);
imagedestroy($dest);
imagedestroy($src);
?>
